S94 - V.25bis Mode Control

Description
S94 provides an alternative to setting internal DIP switches when choosing between the AT command mode (factory setting) and the ITU-T V.25bis command modes supported by the modem. To use this register, the related DIP switches in the modem must be set to select the "AT Command Mode"(factory setting). See the installation information for your modem.

With the modem DIP switches set to select "AT Command Mode" the operating mode after a soft reset is determined by S94. This register is read from nonvolatile memory at power-on; the &W command saves the current setting of this register in nonvolatile memory.
